Okay I a little confused on this and thought someone on here might know the answer. I have a 20 slot breaker box and my main breaker appears to be 60 amps. I would not be suprised to see the service in my house only being 60 amps still since it is an old house but most of the wiring has been upgraded and the wire coming in the house seems newer as well and pretty large (not sure what guage). My question is, is my box actually a 100 amp box and can I get a new meter and service if the line coming in is big enough to go to a 100 amp main breaker and 100 amp service? Are all 20 slot boxes at least 100 amp service boxes? I can't redo the whole thing this year unfortuantely but I want to rerun electrical to the garage and the 60 amp is just not enough to handle it all. I find it wierd that the box has a 60 amp main being in 20 slot box?? I wish I paid more attention in electrical class in High School! LOL! The box does not have service written in the box that it is supposed to be written in.

Well I can give u some sort of clue. If the SE cable coming into the house is #2 alum. you have 100 amps worth of wire at least. The panel should have some sort of rating stamped on it someplace. If it were me d just change it out. A 100 amp panel like that brand new is like 35 bucks.
